Failed to load custom mechanic MMODAMAGE with newest dev builds as of 10/25

Summary

Upon loading server or /mm reload, console is flooded with https://pastebin.com/rkFSp2CG (all of my skills that use MMODAMAGE mechanic)

Steps to reproduce

Load mythicmobs with any skill that contains mmodamage mechanic from mythiclib (phoenix development jars which used to be part of mythic)

Current behavior

All of my mmodamage mechanics do not work as of the newer dev builds

Proposed fixes

I imagine something in the mythicmobs API was changed that removed a depreciated method that MMODAMAGE uses. I believe it was the build 4298 that was supposed to fix this but it never built, and I'm guessing the changes were reverted.
